I know I started fairly late in the game (couple days ago), but luckily a prof I emailed recently expressed interest in having me work at her lab over the summer. Problem is, she's away for a couple weeks and will only be able to meet with me when she returns. The email wasn't an explicit 'yes' (it was more like 'your work is impressive and I would like you to come in to talk about specific projects') but it was fairly positive.
In the meantime, would it be best if I continued applying to other labs in case she eventually doesn't offer me a position? If accepted by other labs, I would really hate to be in a situation where I have to turn down an offer. If it came down to this lab vs. any other lab I am considering applying to, I would definitely choose this one.
Essentially what I am asking is this: in the hypothetical scenario that I apply to another lab and am accepted by them, if I turn them down, what are the chances that I could reapply next year and be accepted?
Thanks in advance for your input! Sorry if anything is unclear.
